Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 30 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate this vulnerability, SWITCH EV and affected organizations should implement strict rate limiting on authentication requests at the WebSocket API level to prevent excessive attempts from a single source. This can include setting thresholds for failed authentication attempts, introducing exponential backoff delays, and temporarily blocking IP addresses exhibiting suspicious behavior. Additionally, implementing multi-factor authentication (MFA) can reduce the risk of unauthorized access through brute-force attacks. Monitoring and logging authentication attempts in real-time can help detect and respond to attack patterns promptly. Network-level protections such as Web Application Firewalls (WAFs) configured to detect and block abnormal WebSocket traffic can provide an additional layer of defense. Organizations should also enforce strong password policies and consider credential hygiene practices to minimize brute-force success. Until an official patch is released, these compensating controls are critical. Finally, maintaining up-to-date threat intelligence and preparing incident response plans specific to EV infrastructure attacks will enhance resilience against exploitation.

Description

The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.

Impact

The primary impact of this vulnerability is on the availability of SWITCH EV's charging services, as attackers can launch denial-of-service attacks that disrupt legitimate telemetry data flow, potentially causing charger outages or mismanagement. This disruption can affect electric vehicle users relying on these chargers, leading to operational downtime and customer dissatisfaction. Additionally, the vulnerability enables brute-force attacks that could lead to unauthorized access if credentials are weak or reused, potentially compromising system integrity and confidentiality. For organizations operating or managing EV charging infrastructure, this could translate into service interruptions, loss of trust, and potential regulatory or compliance issues related to service availability and security. The broad impact is heightened by the fact that all versions are affected and no authentication or user interaction is required to exploit the flaw, making it accessible to remote attackers. The lack of known exploits currently reduces immediate risk but does not diminish the potential for future attacks. Overall, the vulnerability threatens critical infrastructure availability and security in the growing electric vehicle ecosystem.
